Exotic lepton-flavor violating Higgs decays
Journal of High Energy Physics, 2020 Exotic Higgs decays are promising channels to discover new physics in the near future. We present a simple model with a new light scalar that couples to the Standard Model through a charged lepton-flavor violating interaction. This can yield exciting new

Neutrino beam-dump experiment with FASER at the LHC
Journal of High Energy Physics, 2021 The neutrino physics program at the LHC, which will soon be initiated by the FASER experiment, will provide unique opportunities for precision studies of neutrino interaction vertices at high energies. This will also open up the possibility to search for

Search for the t → ch decay at hadron colliders
Journal of High Energy Physics, 2019 We study the observability for the flavor-changing decay of a top quark t → ch at the Large Hadron Collider (LHC) and future hadron colliders, namely, High-Luminosity LHC (HL-LHC), High-Energy LHC (HE-LHC) and Future Circular hadron-hadron Collider (FCC ...

Collider constraints on dark mediators
Journal of High Energy Physics, 2021 We explore the constraints current collider searches place on a QCD-like dark sector. A combination of multi-jet, multi-jet plus missing energy and emerging jets searches is used to derive constraints on the mediator mass across the full range of the ...

Phenomenological Quark Mass Matrix Model with Two Adjustable Parameters [PDF]
Phys.Rev.D49:2638-2641,1994, 1993 A phenomenological quark mass matrix model which includes only two adjustable parameters is proposed from the point of view of the unification of quark and lepton mass matrices. The model can provide reasonable values of quark mass ratios and Kobayashi-Maskawa matrix parameters.

Charged lepton flavor violation and electric dipole moments in the inert Zee model
Journal of High Energy Physics, 2018 The inert Zee model is an extension of the Zee model for neutrino masses to allow for a solution to the dark matter problem that involves two vector-like fields, a doublet and a singlet of SU(2) L , and two scalars, also a doublet and a singlet of SU(2 ...

Journal of High Energy Physics, 2019 Some interpretations of R D ∗ $$ {R}_{D^{\left(\ast \right)}} $$ anomaly in B meson decay using leptoquark (LQ) models can also generate top quark decays through Flavor Changing Neutral Current (FCNC). In this work we focus on two LQs, i.e.

The three- and four-Higgs couplings in the general two-Higgs-doublet model
Journal of High Energy Physics, 2018 We apply the unitarity bounds and the bounded-from-below (BFB) bounds to the most general scalar potential of the two-Higgs-doublet model (2HDM). We do this in the Higgs basis, i.e.

LHC phenomenology of supersymmetric models beyond the MSSM [PDF]
J.Phys.Conf.Ser.259:012002,2010, 2010 We discuss various phenomenological aspects of supersymmetric models beyond the MSSM. A particular focus is on models which can correctly explain neutrino data and the possiblities of LHC to identify the underlying scenario.

Phenomenology of Higgs bosons in inverse seesaw model with Type-X two Higgs doublet at the LHC
Journal of High Energy Physics, 2019 Type-X two Higgs doublet model is known to explain the muon g − 2 anomaly with a relatively light charged Higgs boson at large tan β. The light charged Higgs boson has been searched in the main τ ν mode at the colliders.
